...the world's most energy friendly microcontrollers<br />
The EFM32 <strong>TIMER</strong> module can be used for a number of different functions which include up/down<br />
count, input capture or output compare. Figure 1.1 (p. 2) shows a block diagram with the <strong>TIMER</strong><br />
module overview.<br />
The <strong>TIMER</strong> can be clocked from several sources, both internal and external. It includes a 16-bit counter<br />
with multiple modes, input capture, output compare and PWM. If more bits are needed, the 3 timers can<br />
be connected, resulting in a counter with 32 or 48 bits. Also, it can generate Reflex Signals to trigger<br />
other peripherals such as the ADC, USART or DAC and interrupts to wake up the processor.<br />
